what are these curved mountain roads you refer too? I believe EB PP has summer tires, so if its cold, then you may have the wrong tires for the job.

With 300 HP, or even 435 HP, and season appropriate tires, I don't think it should be that hard to keep the car firmly footed. Now if you had S/C V8 with 650 HP, that's different.


I live at the base of a mountain , lots of fun curvy roads around where I live. I don't want to go super fast on them or anything, but I do want to feel confident when I push it a little bit.

this sure sounds like the domain of AWD. WRX? I will probably take a hit for saying this :headbonk:

Not lol. Looking for helpful guidance here, not a clown dance. :headbonk:
You may not want to hear it but this is the problem you are experiencing. More right foot control is what you are looking for. Sticky tires will just be a bandaid, the problem is you don't realize how much gas you're giving it. I agree these tires don't inspire much confidence. The other contributing factor is the turbo. NA is much easier to control and manipulate how much power you want to put to the ground. Boost complicates that intention, the V6 might have been the better car for you if you are fairly new to RWD. Sticky tires will just increase these limits and when you pass them, they are more dangerous.

I would advise empty parking lot or autocross to help you learn your car better. I very much still need more experience pushing this car to the limit and would like to take my own advice, especially the empty parking lot :D but I've never had a problem keeping the car from getting out of my control, as it sounds like you are describing. The only exception to this is once at below freezing temps and the pirellis were like hockey pucks. Thankfully it was the dead of night and was just pretty much a controlled slide lol. My cousin in the passenger seat got a real kick out of it though haha as I was barely into the throttle.

This was great, thanks for that. I'm definitely interested in some autocross.
I live really close to some nice racetracks that have events, I will look into some specialized driving coaching as well (since I work in the film industry, I do have some contacts with stunt drivers, although I'm sure the race track trainers would probably be sufficient)

But that being said, I think stickier tires would be a big help. I do want to goose the throttle sometimes, just for fun, and I always keep the car under control. I just get annoyed that it gets loose as soon as it does. That's all..

Please tell me more about both of these upgrades.
Especially the brand/model of the tires I should be looking at.

The truth is , I'm not even gunning it. It's definitely the physics in action, but it's a too common occurrence even on wider angle turns..seems to want to let go more easily than I want it to.
Stickier tires would definitely be a step in the right direction.
I don't know anything about suspension upgrades but I am more than willing to investigate.
You may want to pose your questions in the suspension forum and wheels/tires forum to get more specific help on parts specific to your needs.

You have a lot of misconceptions regarding AWD my friend.
probably. I have been motoring around in RWD for a long time on flat Texas roads. Mustang is great car for this. AWD is beyond my pay grade. That said, theoretically AWD would be good for winding mountain roads. I know that such cars can have varying methods of power transfer to the wheels. Some behave more like FWD, and some more like RWD.

This could make an interesting thread, in the Other section of course, "what's the best car for Pacific Coast Highway under $35k

You could look around tirerack.com . They rate some of their tires on various parameters, such as dry and wet traction. Maybe they have your current set of tires rated there, and you can see how they compare.

I have owned alot of turbo RWD cars, you never want the front wheels turned when boost hits and the torque goes through the roof. The problem on the EB is that boost hits very early and very hard.

Once you are moving and keeping it above 3k on the tach in 3rd gear or higher it's a pu$$ycat and I love hitting a winding road with it. But trying to go around a corner in 1st you need a gentle foot or massive rear tires as soon at you hit 2500 rpm, Remember your torque multiplication is 14 times in first gear on a base and 15 times on a PP. that's around 4346 ft/bs trying to accelerate a tire that is trying to hold the lateral force of a 3400 lb car.

I'm hours from picking up my new 2016 GT here in the UK. It's cold and very wet, with flooded roads so after all these threads about the Mustang's ability to go easily sideways and a year's wait since placing my deposit, I'm approaching the car with trepidation.

My daily is a RWD BMW 3 series that I bought back in 1998 and I have driven ferraris, Porsche turbos on the track, as well as owning a Boxster and having the pleasure of a 24 hout test drive in a brand new 997S in conditions similar to today.

I covered nearly 500 miles that day in storm conditions on mostly British A roads and lots of muddy little country lanes.

Not once did the back end go. I was driving it like my motorbike, out braking everyone, fast overtakes etc, I certainly wasn't taking it easy.

Maybe it's the 35 years of motorbikes that have taught me to drive in slippery condition.

It's great fun in the warm and dry and you can get away with all sorts but as soon as the temps drop and roads get slippery, just go smooth and gentle.

I managed a winter in a Grand Marquis, a very rare sight over here and far too large for our roads, I just hope that I won't be posting from a ditch or a hedge later today :D

Just a thought, my sales lady said that customers were getting it sideways in the auto but not in the manual.

Too easy to dial in the power in the auto, perhaps?
